Pre-Measured Concentrates for Preparing 0.1 mol/L and 0.01 mol/L Aqueous Titrants
VWR Sodium Thiosulphate ConvoL NORMADOSE® is a line of pre-dosed concentrates supplied in 60 mL plastic ampoules, formulated for easy and accurate preparation of standard volumetric solutions. These concentrates are intended for dilution to 1 L of either 0.1 mol/L (0.1 N) or 0.01 mol/L (0.01 N) sodium thiosulphate solutions. Designed for iodometric and redox titrations, these reagents offer high precision (titer 0.0995–0.1005 mol/L at 20 °C) and NIST traceability, ensuring consistency in analytical chemistry workflows.
